Expert Solution
Step 1

a) given ratio of height of image h to height of object h' is 

(h/h')= 4.40

And position of the object is u=-12.3cm (using sign convenience)

But we know for mirror

Advanced Physics homework question answer, step 1, image 1

Therefore from mirror formula

Advanced Physics homework question answer, step 1, image 2

This is the focal length of the mirror.
